The question is incomplete, here is the complete question:

A chemist fills a reaction vessel with 9.47 atm nitrogen monoxide gas, 2.61 atm chlorine gas, and 8.64 atm nitrosyl chloride gas at a temperature of 25°C. Under these conditions, calculate the reaction free energy for the following chemical reaction:

Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule.

The Gibbs free energy change of the reaction is -44.0 kJ

Explanation:

The equation used to calculate standard Gibbs free change of a reaction is:

For the given chemical reaction:

We are given:

Putting values in above equation, we get:

We are given:

Putting values in above expression, we get:

To calculate the Gibbs free energy change of the reaction, we use the equation:

where,

= standard Gibbs free energy change = -40.94 kJ

R = Gas constant = 8.314 J/mol.K = 0.008314 kJ/mol.K

T = temperature =

= reaction coefficient = 0.319

Putting values in above equation, we get:

Hence, the Gibbs free energy change of the reaction is -44.0 kJ
